What Are Hive Buckets. Clustering aka bucketing on the other hand, will result with a fixed number of files, since you do specify the number of buckets. At a high level, hive partition is a way to split the large table into smaller tables based on the values of a column(one partition for each distinct values) whereas bucket is a technique to divide the data in a manageable form (you can specify how many buckets you want). What is bucketing in hive. The division is performed based on hash of particular columns that we selected in the table. Partitioning in hive is conceptually very simple: A bucketed table split the data of the table into smaller chunks based on columns specified by. It is similar to partitioning in hive with an added functionality that it divides large. Basically, for decomposing table data sets into more manageable parts, apache hive offers another technique. Present in that partitions can be divided further into buckets; That technique is what we call bucketing in hive. What hive will do is to take the field, calculate a hash. It is used for efficient querying. We define one or more columns to partition the data on, and then for each unique combination of values in those columns, hive. The bucketing in hive is a data organizing technique.
